I dont understand the difference between RO water and RO/DI water. I want to get a RO or RO/DI unit to get phosphate out of my well water. will either work?
Sorry, this is not completely accurate. RO/DI is still the best bet to remove PO4...RO = takes phoshates and all minerals out of the water
Silicates are often found in well water, and from other sources. RO does nothing to limit silicates, but DI controls phosphate, nitrate, and silicates. Therefore, I would recommend DI for everyone. The Tap Water Purifier from Aquarium Pharmaceuticals is a cheap starter kit for a DI system.
This can get pretty expensive. There is still alot of junk in the water, using that set up, when it gets to the DI. Thats why it will only last 25-125 gals.Produces an average of 25 to 125 gallons of perfect aquarium water, depending on the mineral content of your tap water, before a new cartridge is needed.
